H-Bridge Driver

The 33186 is a monolithic H-Bridge ideal for fractional horsepower

DC-motor and bi-directional thrust solenoid control. The IC

incorporates internal control logic, charge pump, gate drive, and low

continuous inductive DC load currents up to 5.0 A. Output loads can

be pulse width modulated (PWM-ed) at frequencies up to 10 kHz.

The 33186 is parametrically specified over a temperature range of

-40

up to 40 V with de-rating of the specifications. The IC is available in a

surface mount power package with exposed pad for heat sinking.
